A blockchain is a shared, digital notebook that many computers keep track of at the exact same time. Instead of trusting one single person or big company to write down important information, everyone on the network has an identical copy of this notebook. Once something is written inside it, it can never be changed or erased, which makes the information completely trustworthy. Traditional systems, like banks, are centralized. This means one master computer controls everything, and if that computer breaks or gets hacked, the whole system fails.

A blockchain is decentralized, meaning the information is spread across thousands of computers worldwide. If one goes down, the rest keep working perfectly. Every page in this digital notebook is called a block. Cryptography is a core security mechanism in blockchain technology, ensuring that transactions, identities, and data remain confidential, tamper‑proof, and verifiable,

Cryptographic hashing is a key part of making blockchain blocks effectively immutable, but it does not make them absolutely unchangeable — it makes tampering extremely costly and detectable. When a block is created, its hash is calculated from its contents (transactions, timestamp, etc.) plus the hash of the previous block. This creates a chain of hashes where each block links directly to the one before it
